[PATCH v2 5/5] dt-bindings: iio: adc: samsung,exynos: Drop touchscreen support

[Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>]

With last user of touchscreen via ADC (S3C24xx SoC) gone, drop the
unused has-touchscreen property and optional touchscreen interrupt for
samsung,s3c6410-adc.  The samsung,s5pv210-adc is the only platform
having two interrupts, so add a constrain for that.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

Changes in v2:
1. Fix S5Pv210 interrupts
